From the 1980's, when fitness meant Jane Fonda, tight, shiny, and neon-bright to the 1990's, when mega-gym's first appeared and everyone wore high-rise bike shorts and scrunchies, and we saw the birth of the late-night fitness infomercials to the 2000's, when there was an explosion in workout options from cycling to kickboxing to Pilates coming into vogue, a yoga booty and weight lifting for women, and interval and heart-rate based training, while wearing capri-length running tights and a technical tank top, to now ... lots to talk about with Molly Fox, one of the true fitness icon's, who has been part of each of these memorable decades of movement.
